Abstract: An incrementally activated laminate that includes an incrementally activated fibrous web and a film having alternating first and second regions and a laminate of the film and an extensible fibrous web. The first region of the film includes a first polymeric composition, and the second regions include an elastic polymeric composition that is more elastic than the first polymeric composition. In the incrementally activated laminate, the distance between midpoints of two first regions separated by one second region is smaller than the activation pitch, and the first regions are not plastically deformed. In the extensible laminate, a tensile elongation at maximum load of the film is up to 250 percent of the tensile elongation at maximum load of the extensible fibrous web. Methods of making the laminates are also described.

Abstract: A film having first and second segments alternating across the film's width direction. The second segments are more elastic than the first segments, and a force required to stretch the second segments is less than a force required to stretch the first segments. At least some of the first segments have apertures through their thicknesses, and a percentage of area of the first segments occupied by the apertures is greater than a percentage of area occupied by any apertures that may extend through the second segments. Laminates and absorbent articles including such films are also disclosed. A method of making the film is also described.
